On September 11th, U-KISS guested on KBS's 'Gag Concert' and showed off their variety skills with a trot remake of their hit track, "Manmanhani". The show's 'Superstar KBS' corner has been a hit for a while now thanks to the many idol groups who've guested on it with their own trot remixes of their songs.  It's a favorite amongst viewers, as they get to see their favorite idols really let loose for the sake of laughter. Three members of U-KISS emerged onto the stage, immediately letting their cool image crumble as they danced to their trot-"Manmanhani".  Still, it must've not been enough, as gagmen joked, "It's funny because they're idols, otherwise it's not funny at all." The members disagreed and immediately brought out three more members.  Although they strolled out looking like their usual cool selves, they busted out some hilarious kkap moves the minute the music began playing, complete with 'kim (seaweed)' stuck to their teeth and a fake runny nose to add to the comedic effect.
